STREET SWEEPER.

UNITED STATES PATENT OFFICE.

JOHN JONES AND ALEXANDER GILLIES, OF TORONTO, CANADA, ASSIGNORS TO JAMESEDWARD KNOX, OF SAME PLACE.

STREET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 599,937, dated March 1,1898.

Application filed June 28, 1897.

- following is a specification.

Our invention relates to improvements in sweepers; and the object of theinvention is to design a simple and easily-adjusted form of auxiliarybrush by which the gutters and sides of the streets may be effectuallyswept; and'its consists, essentially, of a brush connected by auniversal joint to the end of the shaft of the main rotating brush, suchauxil iary brush being suitably journaled on barhangers connected to thebottom of the frame of the wagon, and the parts being constructed andarranged in detail as hereinafter more particularly explained.

Figure l is a perspective view of a streetsweeper provided with ourimprovement, parts being broken away. Fig. 2 is an enlarged perspectivesectional detail of the outer end of the auxiliary brush. Fig. 3 g is aperspective detail of the outer journal-sleeve.

In the drawings like letters of reference indicate corresponding partsin each figure.

A is the main body or floor of the wagon.

B are the front wheels, and O are the rear wheels.

D is the auxiliary circular brush, which is provided with a central axleE, connected by a universal joint 6 to the end shaft F of the main brushG.

D is the hub of the auxiliary brush, which is provided with cup-shapedends D and D which are secured to the ends of the hub D. The hub ispreferably made of wood to receive the bristles of the brush and has theflanges d and d secured to the ends. The inner ends of the cup-shapedends D and D are secured to the axle E.

H is a bracket secured to the lower end of the hanger-bar I, the upperend of which is pivotally connected to the hanger-bracket J, secured tothe bottom of the sweeper. The bracket H has a cylindrical rear end 11,through which extends the sleeve K, having a flanged inner end is, whichprojects behind the inner end of the cylindrical rear end H Serial No.642,583. (No model.)

of the bracket. The inner end of the sleeve K fits also within thecup-shaped end D and has the axle E extending through it.

L is a bracket journaled on the axle F of the main brush G and connectedby the barhanger L to a suitable bracket Z on the bottom of the body.

M is a chain connecting the hanger-bars I and L.

N and O are rods having forked ends a and 0, respectively, whicharepivotally connected to lugs h and Z at the tops of the brackets H andL, respectively.

P isa lever pivotally connected to the top of the rod N, fulcrumed onthe bracket P and extending through the metal strap P secured to the topof the body.

Q is a lever pivotally connected at the top of the rod 0 and fulcrumedon the bracket R.

Q is a lever at the opposite side, also fulcrumed on the bracket R.

S is a connecting-rod connected at one end by the links 8 to the leverQ, and at the other end by link 5 to the lever Q.

T is the operating-lever, which is suitably connected at one end to theconnecting-rod S, is fulcrumed at t on the bracket T and extends at theforward end through the metal strap U, secured to the top of the body.The

holdthe connecting rod and its coacting levers and brushes at anydesired height.-

Having now described the principal parts involved in our invention, weshall briefly describe its utility. The brushes of course are driven inthe usual manner, preferably from the opposite side of the machine tothat shown in the drawings, and the auxiliarybru sh and main brush maybe raised and lowered through the connecting-rods by the lever Thereinbefore described. The chain M, connecting the bar-hangers I and Ltogether, serves to keep the journals of the auxiliary brush D inposition and thereby permit of the rotation of the brush through theuniversaljoint connection e between the ends of the axle E and the endsof the axle F of the main brush. The auxiliary brush formed in themanner such as we describe, it will be readily seen, serves to clean outthe gutters next the curb, as such brush may be raised and lowered atthe outer side into any desired angle through the series of holes at thetop of the rod N.

In utilizing the auxiliary brush we wish it to be understood that thehind wheel is the guide for the driver, as it passes along close to thecurb, and the outside of the brush is situated just inside the wheel, soas to protect it and at the same time utilize-the brush very close tothe curb. It will also be understood that the distance between the frontwheels is very much less than that between the rear wheels.

The sleeve, which is journaled in the rear cylindrical end of thebracket H, is also made to fit such cylindrical end loosely, so that thebearing will not bind when the brush rotates and is in a cantedposition. The sleeve K does not revolve itself, but is held from turningby a feather-key 7c in the cylindrical end, and being loose is permittedof being slightly canted in its bearin \Vhat we claim as our inventionis- 1. In combination, the main brush, the auxiliary brush situated toone end of the main brush and a suitable axle therefor, a universaljoint connection between such axle and the axle of the main brush, thehub, cupshaped ends for the same secured to the axle, the inner andouter end brackets and barhangers connected thereto and pivotallysupported at the bottom of the wagon and means for preventing thelateral displacement of the bar-hangers at their rear ends as and forthe purpose specified.

2. In combination, the main brush, the auxiliary brush situated to oneend of the main brush and a suit-able axle therefor, a universaljointconnection between such axle and the axle of the main brush, the hub,cupshaped ends for the same secured to the axle,

the inner and outer end brackets and bar hangers connected theretopivotally supported at the bottom of the wagon and a chain connectingthe bar-hangers as and for the purpose specified.

3. In combination, the main brush, the auxiliary brush situated to oneend of the main brush and a suitable axle therefor, a universaljointconnection between such axle and the axle of the main brush, the hub,cupshaped ends for the same secured to the axle, the inner and outer endbrackets and barhangers connected thereto pivotally supported at thebot-tom of the wagon, the cylindrical rear end formed in the outerbracket, the sleeve through which the axle extends having an innerflange designed to project against the inner end of the cylindrical rearend of the bracket and means for preventing lateral displacement of thebar-hangers attheir rear ends as and for the purpose specified.

4. In a sweeper'or like machine, in combination the main brush, levermechanism for adjusting the same, the auxiliary brush situated to oneend of the main brush and a suitable axle therefor, a universal-jointconnection between such axle and the axle of the main brush, suitablejournals for the an xiliary brush supported from the frame of themachine, a vertically-ad j ustable rod connected at its lower end to thejournal-box at the outer end of the auxiliary brush, the operating-leversuitably pivoted and connected to said rod and the main-brush-operatinglever extending over the inner end of the auxiliary-brush-operatingleveras and for the purpose specified.
